MAGAZINE PHOTOGRAPHIC CAMERA.

Specification of Letters Patent.

Patented Oct. 2, 1996.

Application filed July 24, 1905. Serial No. 271,010.

1'0 all whom it may concern.-

Be it known that I, HERBERT EDWARD Hroxox, a subject of the King ofGreat Britain, residing at 297 Haydons road, Wimbledon, in the county ofSurrey, England, have invented new and useful Improvements in MagazinePhotographic Cameras, of which the following is a specification.

This invention relates to a magazine photographic camera which isadapted to receive in the daylight a charge of sensitized plates, tocarry a focusing-screen, to convey successively the several plates fromthe magazine to the exposure-chamber, and in the transference to causethe plate to automatically displace the focusing-screen and occupy thesituation thereof and after exposure to drop into avessel containing adeveloping solution, from which it is enabled to be transferred to abath containing the fixing solution, the enire operation being adaptedto be performed without recourse to a dark-room.

The apparatus is specially adapted for the production of ferrotypepositives, and an imortant form of construction will be one suit ablefor taking miniatures.

To facilitate the carrying out of the successive operations aboveenumerated, the following constructive features may be adopted in theseveral component arts, or there may be some departures there cm, asexperience may dictate. The sensitized plates are 0 aque or are mountedon an opaque late, t e rim of which is bent round the e ge of thesensitized plate onto the front thereof, thus providing a thicknessofmaterial whereby the sensitized surfaceis protected from rubbingcontact with the back of the adjacent plate. The plates may be .round,square, or any other shape.

Referring to the accompanyin I drawings,

Figure l is a perspective view s owing the general arrangement andrelativefdis osition of the parts. Fi Z-is a horizonta section takenthrough the center lines of the magazine and exposure chamber s Fig. 3is a rear view with the ivoted solution vessel and case removed. T

his view is drawn as projected from Fig. 2; and Fig. 4 is apartsectional elevation. Fig s.,5, 6, 7, and 8 are detail views. Fig. 1is shown on a smaller scale than theother figures.

In these figures, a 1s her, which on lifting ,the spring-closedlid b isadapted to receive a charge of sensitized.

the magazine-cham-.

, end with a lens g, adapted to springs Which is adapted to suit theprofile of the plates with a sliding fit. The plates are opaque, and thesensitized surface faces in thedirection toward the right in Fig. 2. Thecase,;

lates contained in a case 0, the section of Y at the right-hand end asviewed in Fig. 2, has

an inward-turned flange 0 ,whereby the plates, inserted at the left endof the case, are re vented from passing through. Before filling the casewith sensitized plates aflanged disk c is first inserted, the depth ofthe flangebeing somewhat more than the thickness of the rim-fortifiedsensitized plate. By means of the disk 0 the terminal plate is, While itis in thecase, protected from the action of light. After placing thecase full of plates into the magazine-chamber a the lid 1) is closed anda helical spring (Z is inserted through an aperture at the right-handend, Fig. 2, of the magazine to press on the flanged disk 0 the springhaving sufficient fiexibility,to,1naintain a thrust on the plates andforce them toward the left-hand end of the ma azine,

from the first, when the magazine is. 11, to the last, when all theothers have been expended. The helical spring d is retained in place byclosin the right-hand end of the magazine-cham er. For this purpose acap e, secured by one or more bayonet-joints, maybe used. Side by sidewith the magazine-chamber a is situated the exposurechamber This chamberis fitted at one be adjusted in position for focusing urposes. At theother end is a translucent ocusingscreen h. This screen isspring-mounted on the camera-case, the ends of the two arms it of thespring being secured by screws t i. By means of the i '1' the screen ispressed into the exposure-chamber until arrested by the rim t coming incontact with the edge j of a short tubular extension of the camera-case.

Within the exposure-chambenvery near to the left-hand end, is a partialpartition is, having an orifice therein of the size and shape of theportion of the plate to be exposed, the distance of the partition fromthe near end of the exposure-chamber being just sufficient to permit forthe plate an easy entrance to and exit from the compartment therebyformed. Extending from the partial partition'k toward the lens isa shorttubular extension m, the end of which is commanded byashutter n, whichisnormally spring-closed, but

adapted to be opened-by means ofggpfingerpiece sition. where it can beplate 0 when it is required to focus an object or expose a plate.

For the purpose of transferring a plate from the magazine-chamber to theexposurechamber a piece 1) is provided which is adapted to slide withina slotway formed in the end plate of the magazine-chamber. The piece 1)comprises a foot having a toe p and a eel 12 to which is secured amanipulatingknob 12 p, the ends of which are inserted between the arms'5 i of the spring which carries the screen and the slotted guide-plateof the sliding When the sliding piece 1) is in the direction toward theexposure-chamber, the toe 1) will be in contactwith the rim of a platewhich it is transferring from the magazine-chamber to the compartment atthe end of the exposure-chamber. At the same time the heel p of the footwill be pressed on by the next plate in sequence in the magazine, whichplate will for the time be prevented by the heel from getting into theposition from which it can be transferred to the exposurechamber. Whenafter completing the movementtoward the exposure-chamber the slidingpiece p is returned to the other end of the slide, the foot will sli offthe back of the next plate, which has een pressing thereon, and permitthe rim of that plate to take a powhen p is next pushed toward theexposurechamber. Thus one by one the plates can be transferred from themagazine into the position for exposure. When the sliding piece 1) isinthe position toward the exposure-chamber, its foot will support thenext disk in the magazine-com artment on one side only, causing it to t't relatively to that next in se-. quence and so present an opportunityfor the leakage of light to the sensitized surface. To exclude the lightunder such circumstances, a blind t is provided, one end of which issecured at t to the casing and the other end to,

the spindle which carries the-manipulatingknob The blind wrinkles uploosely when't e sliding piece is moved toward the left, Fig. '1, andstretc esitightly across the slot, as shown inFig. 2, when piece pismoved in the reverse direction.

To enable the focusing to be performed with accuracy, the surface of thescreen is re uired to occupy the exact position which will presentlybefilled by the sensitized film when exposed, and an important featureof this invention resides in the means for automatically displacing thescreen from and replacing it in the position for correct focusing. Forthis purpose the arms '5 i of the spring are bent so as to form recesses'5 '8 which the ends of the pin 19 can temporarily occupy when thesliding piece reaches the end of its movement away from theexposurechamber. When in this position, there is nothing to prevent thescreen from being To the piece 10 is secured also a pin acted on by thetoe p carried by the spring into the exposurechamber to its limitingosition, and when the sliding piece is move in the act of transferringthe next plate the ends of the pin p will by interposing themselvesbetween the arms it and the slotted plate push those arms in such a wayas to remove the screen outward from the exposure-chamber and out of theway of the plate which is being shifted mto the operative position.

the camera-case comprising the Beneat magazine and exposure chambers ismovably mounted a vesse formed with two compartments g 9 This vessel ispivoted in such away as to turn in a horizontal plane about a vertialaxis 1'. In its inward operating position an outward-bent flange isreceived in a groove provided beneath the camera, as at to, Fig. 4. Thisserves to steady the vessel and exclude the light. The movablesolutionholdin vessel contains a cradle s, perforated at the bottom,which cradle is adapted to receive the plate just previously exposedandfacilitate its transference from the compartment g to the compartment (1when the vessel has been temporarily withdrawn from the home positionbeneath the camera-case. The small compartment into which the plate isthrustfor the purpose of exposure has no bottom, but the plate containedtherein is 5 temporarily supported by a ledge 8, formed on the cradle s.The outward-lying edge of the ledge s is bent into a hook form, wherebythe cradle s can be hung on the ed e of the solution-carrying vessel.When a ter the exposure of the plate the vesselis withdrawn a smalldistance, the plate will drop into the cradle s, which at the timeshould occupy the compartment 9, into which has also reviously beenpoured a quantity of deve oping solution. After remaining in thatsolution for a sufficient interval of time the cradle and containedplate are transferred to the compartment g which contains a fixingsolution. After a short time the Iplate should be removed and washed. hevessel is fitted with a sliding lid q", as shown in Fig. 1, which isclosed when the camera is bein carried from one place to another. When te ma azine has become depleted, the flanged dlsk 0 above referred to,will occupy the position of the last plate, and when an attempt is madeto transfer it to the exposure-chamber, the depth of its flangepreventing such displacement, the fact will be made known that themagazine is empty of plates.

To enable the camera to be mounted on anordinary camera-stand or tripodin a sufl icientlyelevated position to permit the developing and fixingvessels to be manipulated, a removable standard 0 is provided. Itconsists of three parts. The screw 12 which after being passed throughthe orifice ordinarily formed in a tripod-head, is screwed into the baseof the standard proper, v, and secured by toe on the a butterfly-nut if,the upper end of the standard being screwed into a socket v, carried bythe under side of the camera.
